LUBRICATION STRUCTURE OF COMPRESSOR

摘要

PROBLEM TO BE SOLVED: To provide a lubrication structure of a compressor for preventing lubricating oil from flowing into a suction room side after stop of the compressor and causing oil pressurization in relation to a lubricating oil channel for returning lubricating oil separated from compressed fluid gas to the suction room side. SOLUTION: A valve mechanism 40 opening at a predetermined pressure difference or more is disposed in the lubricating oil channel 30 for returning the lubricating oil LO that separates from the compressed fluid gas and reserves in a high pressure delivery room HR to a low pressure suction room side LR.
